Does an n-type battery have a pn junction
P-N Junction | Mini Physics
In the p-type region there are holes from the acceptor impurities and in the n-type region there are extra electrons from the donor impurities. When a p-n junction is formed, some of the electrons from the n-region which have reached the conduction band are free to diffuse across the junction and combine with holes.

Diodes: PN Junction, Types, Construction and Working
Since a junction forms between a P type and N type material it is called as P-N junction. The word diode can be explained as ''Di'' means two and ''ode'' is obtained from electrode. As the newly formed component can have two terminals or electrodes (one connected to P-type and the other to the N-type) it is called as diode or P-N junction ...
PN Junction formation and How it works
Then we dope this p-type semiconductor with a pentavalent impurity (Phosphorous or Arsenic or Antimony ) to form an n-type region on the same wafer. Thus we have made a p-type and n-type semiconductor on the same wafer, resulting in formation of a junction (between p-type and n-type semiconductors) on the same silicon wafer.
Bias of PN Junctions
As in forward bias, the drift current is limited by the number of minority carriers on either side of the p-n junction and is relatively unchanged by the increased electric field. A small increase in the drift current is experienced due to the small increase in the width of the depletion region, but this is essentially a second-order effect in ...

Reverse Biased PN Junction Diode: Definition and Characteristics
Therefore, this is termed as P-N Junction Diode. When the two types of impure semiconductors are blended, charge carriers (free electrons and holes) begin to travel through diffusion at the junction. Holes emerge from the P-Type semiconductor and travel into the N- Type one, electrons come out from the latter diffusing to enter the former.
The photovoltaic effect
In order to generate power, a voltage must be generated as well as a current. Voltage is generated in a solar cell by a process known as the "photovoltaic effect". The collection of light-generated carriers by the p-n junction causes a movement of electrons to the n-type side and holes to the p-type side of the junction. Under short circuit ...

PN Junction Operation
With reverse bias, the electrons in the P-type material are repelled toward the junction by the negative terminal of the battery. As the electron moves across the junction, it will neutralize a positive ion in the N-type material. Similarly, the holes in the N-type material will be repelled by the positive terminal of the battery toward the ...

Formation of a PN-Junction
P-n junctions are formed by joining n-type and p-type semiconductor materials, as shown below.Since the n-type region has a high electron concentration and the p-type a high hole concentration, electrons diffuse from the n-type side to the p-type side.Similarly, holes flow by diffusion from the p-type side to the n-type side.If the electrons and holes were not …

PN Junction Theory
As a result, the charge density of the P-type along the junction is filled with negatively charged acceptor ions ( N A ), and the charge density of the N-type along the junction becomes positive. This charge transfer of electrons and holes across the PN junction is known as diffusion.The width of these P and N layers depends on how heavily each side …

The behavior of a semiconductor diode can now be understood. If the positive side of the battery is connected to the n-type material, the depletion layer is widened, and the potential energy difference across the p-n junction is increased. Few or none of the electrons (holes) have enough energy to climb the potential barrier, and current is significantly reduced.
